Abstract
A gyroscope which has a spinning fluid filled annulus as an inertial angle rate sensor is compensated for inertial drift by resolving an output signal from the sensor into acceleration proportional components related to the gimbal axes and the component related to the inner axis is applied to the outer axis, and the component related to the outer axis is applied to the inner axis to cancel out the effects of drift.
